Compact 4-Channel Passive Mixer

The PROZOR 4-Channel Passive RCA Mixer combines four stereo sources into a single output without any external power supply. Its metal housing measures 83 mm by 52 mm by 38 mm and weighs 280 grams, making it a portable solution for home studios, DJ sets or simple TV and PC mixing tasks.

Suited for Simple Line-Level Mixing

This unit suits users who need independent volume control for up to four RCA sources such as CD players, instruments or computers. It is not for buyers who require microphone preamplifiers, phantom power, equalisation, headphone monitoring or any active gain stage beyond the passive -12 dB maximum attenuation.

Plug-and-Play Installation

Installation is limited to connecting RCA cables to the gold-plated ports and adjusting the four rotary knobs; no drivers or configuration are needed. The only common issue is signal loss if source impedance falls far outside the 10 kΩ to 47 kΩ input range, or if the connected amplifier expects a higher level than the 2.5 kΩ to 10 kΩ output can deliver.

Questions about this item

Which sources do I need to have ready with RCA outputs to connect to the four channels?

Any stereo device with RCA outputs — TV, PC, CD player or instrument — can feed each of the four channels independently.

Will the mixer change the sound of my older amplifier that expects a typical line-level signal?

The passive circuit has a maximum gain of -12 dB and an output impedance of 2.5K to 10K ohms, so it attenuates slightly and matches standard line inputs without colouration.

How can I verify the mixer is passing audio correctly once everything is plugged in?

Play a source on each channel, raise its volume knob and confirm clear, undistorted sound at the amplifier; the gold-plated RCA ports and metal housing ensure a clean path.
